scm_m_generalized_set_x, scm_init_evalext): Move the declaration
and definition of the memoizer for the generalized set! macro from
evalext.[ch] to eval.[ch]. Use the SCM_SYNTAX snarfer macro to
define the macro object.
* eval.c, eval.h (s_set_x, scm_s_set_x, scm_m_set_x,
scm_m_generalized_set_x): Since now scm_s_set_x is only used in
eval.c, it is made static and renamed to s_set_x.
* evalext.c (scm_defined_p, scm_m_undefine): Prefer !SCM_<foo>
over SCM_N<foo>.
* psyntax.ss (self-evaluating?): Removed. Guile now provides this
operator as a primitive procedure.
(build-data): Quote vectors (psyntax.ss requires this).
having to do with evaluation.
* evalext.c (serial-map): New procedure: Version of `map' which
guarantees that the procedure is applied to the lists in serial
order.
(sequence->list): New syntax: Version of `begin' which returns a
list of the results of the body forms instead of the result of the
last body form.
(scm_definedp, scm_m_undefine): Moved from eval.c
* evalext.h (scm_m_sequence_to_list): Added declaration.
* Makefile.am: Added evalext.c, evalext.h, macros.c, macros.h.
